1. While your oven is preheating to 180 degrees, start by preparing the tomatoes. After cutting the tops, spoon out the inside of the tomatoes, but make sure to keep the tops and flesh.
2. Place your tomatoes evenly into a greased baking dish.
3. Now prepare the filling. Start by sauteing the diced onions first. Add the minced lamb as soon as they turn translucent. Break up your meat whilst browning it. Now add all the spices.
